The Influence of Endoscopic Injection Sclerotherapy on Organs Surrounding the Esophagus

Abstract: Endoscopic injection sclerotherapy (EIS) is widely accepted as a means of treating esophageal varices. However, various complications of EIS have been reported. To investigate the cause of chest complications after EIS, chest CT and bronchofiberscopy (BF) were carried out in patients undergoing EIS. A contrast medium was added to the sclerosant in a 1: 4 ratio, and a chest CT examination was performed 30 minutes after the EIS procedure. BF was performed before and after EIS.

A case of an intra-atrial tumor thrombus from hepatocellular carcinoma (HCC), first indicated by67Ga-citrate scintigraphy

We encountered a very rare case of an intra-atrial tumor thrombus from hepatocellular carcinoma (HCC). Conventional XCT and US gave evidence of HCC. In nuclear medicine studies performed incidentally, the first study with99mTc-phytate liver scintigraphy showed 2 SOLs and evidence of chronic liver disease, and the second study with67Ga-citrate scintigraphy demonstrated 2 hot lesions within the liver parenchyma, and also another unexpected hot area just above the left lobe of the liver, seemingly beyond the diaphragm. When echocardiography was performed, in addition to ECG, because the patient began to complain of dyspnea, an oblong mass lesion was detected within the right atrium. Reexamination with XCT and angiography clearly proved the existence of an intraatrial tumor thrombus. These results indicate the need for routine examination by echocardiography for HCC patients complaining of dyspnea.
